Diễn đàn hỗ trợ Firefox

Hello, For whatever reason, I can't view Youtube livestreams or movies, and the quality on regular videos is limited to 360p only (with some offering the upgrade to 720p - though this often causes the video player to freeze). I've tried disabling my adblocker, my other various plugins, even opening the blocked content in a private window or troubleshooting mode - still no dice. Is this yet another one of Youtube's anti-firefox tricks? is there any way to fix/bypass this?

I would like to select and delete a subset of user names and passwords in Firefox. I have a group of about 80 logins for an old account which I no longer use. I know I can delete individual logins one at a time but doing this 80 times is a pain!

I can search for the particular account in the password list and Firefox lists them all, which is great. What I would like to do then is right click and select all followed by delete.

Is there a shortcut somewhere?

For some reason I updated to win 11 and now Firefox won't let me login to mercadolibre, it will display the login screen, take my username, send me to the password window, enter my password but won't go anywhere from there. The curious thing is that Edge will log me in without any issue and if I do the same thing with Firefox using a private windows it will let me login but Mercadolibre will always ask me to scan a code with my phone which makes the process longer and tedious.

I cleared all the cookies from my system to no avail.

How can I set tabs to automatically preload when I open the browser? I'm just trying to switch from Chrome to Firefox and I can't find such a setting here, although it is a very convenient functionality. I mean that when I open the browser, I can click on any of the tabs and it will be (partially or completely) immediately ready to work without additional loading.

picture-in-picture for videos on the normal instagram feed and posts. It worked last week, it doesn't work now. The little black square doesn't show up on hover anymore, I can't right click at all on videos now.

I'm trying to use a manual proxy server for Firefox. When entering the proxy address and port number, Firefox outlines the port number field in red and disables the OK button thus refusing to accept my assigned port number. I'm trying to use port number 29842 which was given to me by the proxy provider.

So I've been doing this for years now, as a Youtuber I take an image file from File Explorer (Windows 10) and drag it over to upload the thumbnail to Youtube. But for some reason the last few days I can't drop the file, it just stays there with the mouse when I let go of the button. On a random page it should let me drop the file and show the image but it doesn't, and it also won't drop if I try a google image search.

I have tried this on Edge and Chrome and the problem only seems to exist on Firefox.

[My screenshot button hides the mouse in pictures but it's attached to that blue semi-transparent square, trying to drop a file but can't.]

Support,

The USPS website does not work properly with Firefox!! The Home page loads okay but there are multiple other issues with links not working. For instance all of the links under Quick Tools do not work except this one: https://www.usps.com/manage/po-boxes.htm. Other things don't work either.

Everything works fine that I tried with Google Chrome though! Please address soon.

Thanks

Firefox has a magnifier in the url bar. It activates for no reason. The arrow pointer does not move but the magnifier keeps going up and down 110%- 145%- 38% all over the place. only hitting escape several times and then touching the magnifier resets it back to 100% {normal} is there a way of eliminating this feature alltogether? Any help would be appreciated.

Hi, Avast Antivirus keeps giving me this warning every few minutes. I have never visited the site in the URL and it seems to keep appearing regardless of anything I do. Is anyone else getting this? Does anyone know how to fix it?

Thanks.

I thought I had two different accounts. Home, with my personal email and work, with my work email. My work computer crashed a few months ago, and out IT department was able to recover all my bookmarks, but it wasn't easy, so I was told. I decided to do what I do at home and that was to create an account for work, which I did. I now have an account for home with it's own bookmarks, and email, and a work account with it's own bookmarks and totally different email. I recently got a work phone. In the process of setting it up I synced it up with my work account. when I came home tonight I got online and all my work bookmarks were on my home computer. How did this happen? Now I don't have my home bookmarks. I tried signing out and signing back in with my home account, but no luck. This is very frustrating especially since they are two totally different accounts. SO, how do I get my home bookmarks back on my home computer? Thanks

Trying to stream shows on Firefox and video does not start / errors out. Philo returns with this error: Philo is having trouble streaming this content.

[Error code: pf-1.5-5bb2f]

Paramount+ Also freezes up and returns error message. As does Amazon Prime.

Adblockers disabled. Youtube is fine.

Tried refreshing Firefox / renistalling but same error. Prefer to use Firefox as default browser but having to go to Google to stream shows.

Debating rolling back a version but it was working fine the other day but could have had an update and didn't notice and now streaming is erroring out.

Suggestions? Thanks.

I encounter this message "Peer’s Certificate has been revoked. Error code: SEC_ERROR_REVOKED_CERTIFICATE" when connecting to "Site A" using Firefox version 122.0 (64), my primary browser. I have successfully connected to "Site A" using Firefox in the recent past.

I can connect to "Site A" without errors using my backup browser, MS Edge Version 121.0.2277.83 (Official build) (64-bit).

This seem to be a Firefox related problem.

I have been trying to solve this problem on and off for about a year now, but 99.99% of the time I try to access https://en.wiktionary.org/ , I get the following error: Secure Connection Failed An error occured during a connection to en.wikitionary.org PR_END_OF_FILE ERROR Error code: PR_END_OF_FILE_ERROR

I have NEVER gotten this error message for any other website. And the strangest thing? Sometimes I CAN access Wikitionary with zero problems, but this phenomena tends to only happen when I attempt to access the website very late at night or really early in the morning. I cannot think of a single thing I have done differently when this happens.

By the way, I am able to access Wikitionary from Microsoft Edge just fine, it is ONLY Firefox where I have this problem.

I restarted my computer today and downloaded a new version of Firefox. When I started it up again everything was gone... all Tabs, history, and bookmarks. This is a sad loss as I have been organizing my life with Firefox for over 10 years. Is there any going back and getting my firefox restored?

I am on arch linux running wayland, and whenever I visit some webpages (example reddit, github) some character are displayed incorrectly: spaces are incredibly large and numbers appear as . or , or other random punctuation or don't appear at all

Hi, this is the same issue as as described here for Mozilla Thunderbird: 64bit Thunderbird issues with 64bit PKCS#11 drivers

– Firefox 122.0 (64-bit) – Windows 11 Pro 64bit (– Thunderbird 64bit)

Even though, I use a 64bit version of Firefox, it is not able to load any 64bit PKCS#11 module for security devices. Tried on several different PCs and several different 64bit PKCS#11 drivers for different smart cards.

When I try to load e.g. C:\Windows\SysWOW64\eop2v1czep11.dll for the Czech eID, it returns "Unable to add module". When I do the same from C:\Windows\System32\eop2v1czep11.dll, it works.

The issue is that some issuers of qualified and commercial certificates (like e.g. Komerční banka) do not issue a 32bit version of PKCS#11 drivers for their smart cards anymore and the only driver available is C:\Windows\SysWOW64\mopkcs11.dll, which cannot be loaded by Firefox or Thunderbird either.

I don't see a problem in implementing the support for 64bit PKCS drivers in a 64bit browser and a 64bit email client. And if it does have the support, then there is something wrong going on.
